Someone posted about Vergil: "Also, really, it is Vergil. Can you imagine this collected, ice cold person "hanging out" with anyone?"

Well it could be the same situation as it is in Tekken With Kazuya Mishima & Jun Kazama. Kazuya is near enough pure cold hearted and evil and Jun is a symbol of complete pureness. Yet Namco have just left the storyline as "they were mysteriously drawn to each other" and then Jin Kazama was born. Maybe Vergil was "mysteriously drawn" to someone in the demon/human world and BOOM Nero was born, that is of course assuming Nero is Vergil's son...

Before people say it, yes Kazuya and Vergil are similar in personality in parts, and they both have demon/devil powers within them which they can control.
